The protector positioning jig 300 fixes a positional relationship between the reference protrusion 301 positioned at an apex of the dome part 24 and a fitting part 306 fit into a penetration hole 42 of a dome part protector 40 by a support part 304. Then, the dome part protector 40 is positioned at the apex of the dome part 24 by the fit of the fitting part 306 into the penetration hole 42. |
